Wasn't it the original TT by the late Tom Fletcher? If so it may be worth contacting Nottingham Analogue to see if they can still service the deck. They are usually very helpful over any past equipment.
I don't know how upto date this link is:http://nottinghamanaloguestudio.com
Worth servicing? Of course. It was a well received table in its day. And a piece of history.
The link is to the U.S. importer's site, unfortunately. NA don't have their own website.
